Required packages

[richardcoca]

Hi there,

I'm struggling with loading the necessary packages for this. I have installed these packages, but they seem to not be loading, which leads to some error messages down the line. Are these all the packages required/what syntax was used to the install the packages (if that has an effect)?

library("destiny")
library("ggplot2")
library("patchwork")
library("plotly")
library("scater")
Error: package or namespace load failed for ‘scater’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
there is no package called ‘irlba’
In addition: Warning message:
package ‘scater’ was built under R version 4.0.4

Hello @richardcoca,

You need to install irlba in order to load scater. I don't know what command you used to install your packages, but I like to use the Bioconductor utilities because it takes care of all dependencies for me (I'm lazy and I don't like struggling with dependencies 😉) Using this command works on my side:

install.packages("BiocManager")
BiocManager::install("scater")

Another thing is that I see you have a warning package ‘scater’ was built under R version 4.0.4. What version of R are you using? If the the trick above did not work, you may want to update your R (https://www.r-project.org) to at least that version (I'd recommend using the latest version).
